VALVE-COUPLING FOR PN EUMATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 729,129, dated May 26,1903. l

Application iiled February 27, 1903. Serial No. 145,414. (No model.) y

T0 all whom, t may concern:

Be it known that I, ALBERT BAXTER CAT- TERALL, a citizen of the UnitedStates, residing at Davenport, in the county of Scott and State of Iowa,have invented a new and useful Valve-Coupling for Pneumatic Tires, ofwhich the following is a specification.

This invention relates to certain improvements in air-valves adapted foruse on bicycles, automobiles, and other vehicle-tires.

The object of the invention is to provide a simple, inexpensive, andeiiicient device' of this character which may be quickly applied to andlocked in position on the valve-casing, the relative disposition of theseveral parts being such as to permit the cap being quickly detachedwhen desired and the pump-tube coupled with the valve for inating thetire.

A further object of the invention is to provide. a valve in which theusual threaded cap or cover is dispensed with, the end of thevalvecasing and the cap, as well as the air-tube connection from thepump, being provided with interlocking parts which when secured togetherform an air-tight coupling effectually preventing the escape of air.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustratedl in theaccompanying drawings, and pointed out in the claims hereto appended, itbeing understood that various changes in form, proportion, and minordetails of construction may be resorted to without departing from thespirit or sacriiicing any of the ad! vantages of this invention.

In the drawings, Figure 1 is a side elevation of a valve-casing and capconstructed in accordance with inyinvention. Fig. 2 is a transversesectional view of the same. Fig. 3 is a detail perspective view of thecollar or sleeve detached. Fig. 4 is a vertical sectional view of thesame. Fig. 5 is a side elevation, partly in section, showing a modifiedform of collar or sleeve in which the collar is formed integral with thevalve-casing. Fig. 6 is a bottom plan view of the cap or cover. Fig. 7is a side elevation of the pump-coupling. Fig. 8 is a vertical sectionalview thereof, showing a section of pump tube attached thereto. Figs. i)and 10 are modified forms of the cap or cover and hose-coupling, andFig. 11 is a further modification of the cap or cover.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings. i y

1 designates a section of a vehicle-tire, and 2 the valve-casing, whichmay be of the usual form and construction, being secured to the tire inthe ordinary manner. An interiorlythreaded sleeve 0r collar 3 engagesthe threaded end 4: of the valve-casing, and this sleeve or collar isprovided with an inwardly-extending annular (lange 5, which rests uponthe end portion of the valve-casing when said collar is screwed to itsseat. the sleeve or collar is also provided with an inwardly-extendingiiange having coincident and preferably rectangular openings 7 formedtherein, deininga pair of inwardly-extending segmental plates 8, theunder sides of which are inclined or beveled in opposite directions, asshown at 9. The lower end of the sleeve or collar is provided with aseries of radiallyprojecting upturned spring arms or fingers 10, adapted,to engage an annular groove or channel 11, formed in the lower portionof a cap or cover12, and by means of which the cap is secured inposition on the valve. The cap 12 is provided with a central dependingtube 12', having oppositely-disposed ears or lugs 13, which t within theopening 7 when the cap is placed in position, and the cap may besecurely locked to the valve-casing by giving the saine a halfturn tothe right, which causes the ears 13 to engage the lower inclined facesof the plates 8, iirmly clamping the parts together. A packing ring orWasher 14, formed of rubber or other suitable material, is interposedbetween the tube 12 and the interior walls of the cap and preferably atthe top thereof, said washer resting against the top portion of thesleeve or collar, as shown. The depending tube 12 is formed with anannular shoulder 13', which rests on the flange 5 when the cap is inposition, preventing the escape of air, and said tube is also providedwith a hollow extension `15, adapted to receive the stem 16 of thevalve, as clearly shown in Fig. 2 of the drawings.

InFigs. 7 and 8 I have shown a section of a pump-tube having a novelform of coup The upper end of l Ioo ling secured thereto and adapted tobe used in conjunction with the valve for iniiating the tire. Thecoupling consists of a cup- Ishaped casing 17 of substantially the sameconstruction as the cap 12 and adapted to be interchanged therewith whenthe tire is in- Hated, the lower,end ofV the casing 17 being providedwith an annular groove l9, which engages the spring-arms'lO on the valvewhen the pump is coupled. The coupling is provided with a hollowthreaded tube or extension 18, which screws within the pump-hose, andthe lower end of said tube passes through the top of the casing 17 andis provided with outwardly-extending lugs 19, adapted to enter theopenings 7 in the collar 3 and engage the inclined portion of the plates8, securely locking the pump to the valve. The lower 'end of theextension 18 is also provided with a washer 2O and an annular collar18', adapted to bear against the inwardly-extending flange of the sleeveor collar 3 and prevent the escape of air while inflating the tire.

In assembling the several parts comprising the valve the sleeve orcollar is first screwed on the threaded extension of the valve, afterwhich the cap or cover is placed over the collar and forced downwardlyuntil the lugs 13 register with the openings 7 in the segmental platesand the spring-fingers 10 engage the annular groove in the cap. The capis then given a half-turn to the right, which causes the lugs 13 toengage the inclined faces of the plates 8, securely locking the partstogether. When it is desired to inflate the tire, the cap may be removedby turning the same to the left and pulling upwardly thereon, causingthe spring-ngers to become disengaged from the groove and allowing thelugs 13 to pass through the openings 7. The pumptube may now be attachedby simply sliding the casing 17 over the collar or sleeve until the lugs19' register with the openings 7 and the groove in the casing engagesthe lingers 10, when the parts may securely lock in the manner beforestated.

In Fig. 5 I have illustrated a modied form of the invention in which thecollar or sleeve and the valve-casing are formed integral.

In Figs. 9 and 10 I have shown a modified 'form of cap for the valve andpump-coupling, respectively, the cup-shaped casing in each instancebeing provided with one or more longitudinal slits forming a series ofspringarms 21, the lower ends of which are provided with an annulargroove or recess 22, adapted to engage the spring-arms 10 on the valvewhen the parts are coupled. If desired, the lower part of the cap 12 andthe cup-shaped casing 17 instead of being provided with a groove orchannel may be formed with 'an annular rib 23, as shown in Fig. 11.

From the foregoing description it will `be seen that I have provided Vacap capable of being quickly applied to or removed from the valve, whicheectually prevents the escape of air and being locked both on the insideand outside lessens the liability of said cap becoming loose anddropping off in riding over rough uneven roads, as often happens withcaps in use on valves at present.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A device of the class described comprising, a valve-casing, a cap orcover fitting over' the valve-casing said valve-casing and cap beingprovided with interior and exterior interlocking parts.
